-v`Louis, Missouri, haveinvented4 a certain new and'useful ll'nprovement in Roller- Bearings, ofwhich the following is a full, clear, andeXact description, such as will enableothersskilled in the art to which it appertains to make and fuse the same, reference being had-to the accompanylng drawings, forming part of this specification.

My invention relates-to a roller bearingy for axles, shafts, spindles and the like, the principal object oiy my inventiongbeing to providea comparatively -simpleand inexpensive roller bearing which eanbe readily adjusted to take up wear or lost motion and` which bearing. in addition to being highly efiicient in the reduction of frictionbetween the cooperating parts,`is designed so as to reduce to a. minimum thefriction resulting -from end thrusts or side strains which may be developed between the the bearing is associated. M

Further objects of myr invention are to construct a rollerv bearing having a minimum number of parts, the same'being ar- .rangedso as to be easily assembled or taken a art.v

pWhile my improvcdroller bearing is particularly designed for use in connection with the axles and differential shafts of motor vehicles, vpower boats. aeroplanes and the like, it will be readily understood that saidI bearing can be advantageously utilized in connection with lall forms of machines and structures wherein shafts, axles and spindles are essential parts- With the foregomgand other objects 1n view, my` invention consists in certaint n'ovelA7V portion of' one of the bearing rings and an'y s petmcanmi of Letters raient.

adjustable bearing sleeve and showing' the."

means utilized for locking said parts to each other. 4 l Iiigs.y (i, 7 and 8 are sectional viewssimilar to Fig. l and illustratingr various Inodiiied tforms of |n\ '.in|p.ro\'ed rollerbearing;U

In the construction of the bearing as illustrated i n Figs. 1 to 5 inclusive, -10 designates a hollow cylindrical hub,'one end [of which.

6? i is internally threaded asdesignated-*by -1^1 f .1.

and the. opposite end being provided-with j.

an inwardly projecting Bange 12,;.and the inner edge osaidlange is rabbejted asf des- ".3

ignated by I3.

The end oi' an axle 1.4 is reducediinfdiaine u ter to form a. spindle '15 which foeeup outer end of said spindle is threaded d ignated by 16 to receive a .clamping nuff. 17 if 1anda lock nut 18.

Atthe inner en d of spindle 14 is. formed a shoulder 19 and immediately :id-jacent thereto is a second shoulder 20 l within the rabbet 13. Positioned within the `space between this shoulder andrabloetr is a packing ring 21, preferably of yielding compressible material.

losi-tioned ,on spindle 15j is a pair of hardened metal bearingsleeves 22 and 23 ,and` interposed between 'said sleeves is 1 a, hardened metal ring-'24, the same beinglprovided withapair' of oppositely arranged inlined which is formed' an abrupt shoulder 25, This ring is fixed to-shaft;l5 by means of a key 26, and the ends of said key extend into notches 27 formed in the adjacentends of The outer endv of y"the sleeves 22 and 23. Sleeve 23'bears directly against shoulder 19 and formedintegral with the axle and at the point Whe-re said shoulder is formed are two or more lugs 28 which project into, .corresponding notches 2 9 formed in the end of said sleeve 23. Thus sleeves 22 and23 and .bearing ring 24 are connectedto the'V spindle so as to rotate therewith and said parts are held against long ,ritudinaly movement' upon said spindle by clamping nut `17 vwhich normally bears against the outer end of sleeve 22 and being so, heldby lock nut 18.- (See Fig. l.)

.bearing faces25 at the outer .end of 9()v Positioned against the innelface lof hub.:

l0-and directly opposite the bearing sleeves 22 and 23 are hardened metal bearing sleeves 30 and 31. Sleeve() is connected 'to hub 10 so as to rotate therewith by screws 32 which are seated in the outer portion of said hub and enter longitudinally disposed slots 33, the same being formed in said sleeve. Sleeve 31 is connected to hub 10 so as to rotatel therewith by set screws 34 which are seated in the inner end of said hub and enter notches 85 formed in the outer end of said sleeve.

Seated in the internally threaded outer end of the hub l0 is an adjusting ring 3G, the same bearing directly against the outer end of sleeve 30 and bearing against this ring and serving as a lock therefor is a screw plate 37 which closes the outer end of the hub.

lnterposed between the Sleeves 22 and 30 is a series of hardened metal rollers 38 and positioned between sleeves 23 and 3l is a corresponding series of rollers 39. The rollers of both series are preferably solid and provided at their ends with trnnnions 40 which are loosely mounted in short radially arranged slots 4l. the latter being tormed in rings 42. There is a pair of these rings for each series of rollers and the rings of each pair are connected b v longitudinally disposed pins the ends of which are rigidly fixed to said rings in any suitable manner.

Loosely mounted upon the pins 43 are hollow rollers 44. the same heilig formed of hardened metal and serving the same purpose as the rollers 38 and 39. Arranged adjacent to t-he inner ends ot the two series of rollers 38 and 39 are hardened metal rings 45.y the same being provided with inclined bearing faces 46 which are positioned directl'v opposite the inclined hearing faces 25 on ring 24 and at the outer ends ot these bearing faces are formed shoulders 46a. These bearing rings 45 are held against rotary movement by means ot lugs 47 which are formed integral with said rings and project laterally into corresponding notches 48, the latter being formed in the adjacent ends of sleeves 3() and 3l. (See Fig. 5.)

The inclined faces 46 of rings 45 are oppositely disposed with respect to the corresponding faces 25 ot'A ring 24, and thus annular spaces or chambers are formed between the bearing rings 25 and 45 and which spaces or chambers gradually taper in width toward the axis ot the bearing. Loosely mounted within these annular chambers or spaces are rings 49 and loosely mounted in radially arranged openings therein are short truncated conical rollers 50, the peripheries of which bear against the inclined bearing faces and 46. and the outer ends ot which bear against the shoul ders 2. a and 4t?. By providing these shoulders 25 and 46, the tendency of the rollers to move radially outward `under excessive strains is limited and the greater portion ot such strains is relieved from .the rings 49. These rollers 50 are heldin position within 1,2:samsov the openings in said rings by means of thin metal plates 51 which are fixed in any suitable manner to the sides of rings 49 and with the ends of said plates projecting beyond the sides of the roller openings. (See Fig. 4.)

During the operation of the form of roller bearing just described, the hub revolves around spindle 15 and the two sets of rollers 3S and 39 bearing on the hardened metal sleeves 22, 23. 30 and 3l are effective'in transmitting all radial strains from the hub to the'n spindle or vice versa, and likewise said rollers are. instrumental in reducing to a minimum the friction between said parts.

All end thrusts or strains between the hub and axle are taken care of and the friction resulting from such end thrusts is reduced to a minimum by the hardened metal conical rollers 50 which bear on the inclined surfaces 25 and. 46 of rings 24 and 45.

When it becomes necessary to adjust the position of rings 45 with respect to the rollers 50 for the purpose of taking up wear or lost motion which may develop after the bearing has been in service, cap plate 37 is removed and ring 36 is screwed inwardly, thereby moving sleeve 30 inwardly and consequently causing bearing ring 45 at the inner end of said sleeve to move into engagement with the adjacent rollers 50.

It will be understood that hearing ring 24 is fixed on spindle 15 so that after the position of the first one ot' the bearing rings 45 has been adjusted as just described` further movement imparted to ring 3G will tend to draw the hub outwardly upon the spindle with the resultV that sleeve 3l will cause the bearing rings 45 with which it is in engage ment to move toward the adjacent rollers 50, and thus the lost motion due to wear or other causes will be taken up and the desired results accomplished.

lt will be understood that by providing the slots 33 inI which the inner ends of screws 32 engage that sleeve 30 can be adjusted lengthwise as just described and at the same time said sleeve will be held t revolve. with the hub.

In the construction illustrated in Fig. 6, the axle 52 is provided with a tapered spindle 53 and upon which latter is mounted a hardened metal sleeve 54. llub 55 is provided with an internally arranged hardened metal sleeve 5G. the opening through which is tapered and interposed in the tapered annular space between sleeves 54 and 5G is a series of tapered rollers 57. the. trunnions of which are journaled in rings 5S.

Located at the inner end ot the hub and hearing against a shoulder on the axle 52 is a ring 59 having an inclined bearing tace against which engages the peripheries of a series of radially disposed truncated conical rollers 60. These rollers are carried hy a ring-61 and arranged Within the hub and bearing against an internal shoulder formed therein is a bearing ring 62, the same being positioned on Athe opposite sides of the rollers 60 from ring .59.

lVhen this form of roller bearing is irst positioned in the hub a number ot .comparatively thin Washers 63 are positioned between ring 62 and the inner end of sleeve 56 and as wear takes place and lost motion develops, these washers are removedr one at a time and positioned at the outer end of sleeve 56, thus permitting said last mentioned sleeve and the rollers 57 to be moved inwardly with respect to the hub 55 to compensate for the Wear and which action in nowise changes the relative positions 'of the hub and axle.

In Fig. 6 a single one of these Washers 63 isvshown'positioned at the outer end of sleeve 56. Bearing against this last mentioned washer is a hardened metal ring 64,

' against the outer face of which bears a series .of truncated conical rollers 65,the same belng carried by a ring 66.

The outer end of the tapered spindle is threaded designated by 67 and screw seated thereupon is a ring 68, the inner face of which bears against the rollers 65.

Seated on the outer end of the threaded por-1 tion 67 of the spindle is a lock nut 69 and screwed into the outer end ofhub 55 with its inner end normally bearin against the edge of ring 61k is a screw cap 0. i i

./Vhen screw cap 70 is tightened against ringllt, said ring, together with sleeve 56 and ring 62 will be locked to hub 55 and .f 'consequently will rotate therewith while rings 59 and 68 and sleeve 54 will rotate i .loads or stresses between the spindle and. "lfub and likewise reduce tol a minimum the ,with the/axle and spindle.

'l 'The rollers 57 take care of theA radial friction between said parts, and the rollers and 65 take care of theend thrusts or strains andreduce to a minimum the frictionl incident thereto.

As hereinbefore stated, one of the washers 63 at the inner end of sleeve 56 can be transferred to the outer end of said sleeve when it is desired to take up wear or lost motion, thus slightly changing the position ot' the sleeve 56 with respect to the hub, but without changing the relative positions of the hub and axle.

When ring 68 is tightened upon. the spin dle. said ring, together with rings 64, 62 and 59 will be brought into Vbearing engage# ment With the rollers 60 and 65.

In the form of roller bea-ring illustrated in Fig. 7. a series of comparatively lcng cylindrical rollers 71 are interposed between the spindle 72 and an internalsl ried by hub 74 anda series f truncated conical rollers 75 are arrangeiilbetwen pairs easily sleeve,

rollers 71v and the ends ot' the hub. The

ofy bearing rings 76 between the ends of said outer oneof the rings 76 is screw seated on the end of the spindlein order that the parts may -be-adjusted to take upV any lost motion which maybedeveloped through wear or other causes. y

'The formv of device illustrated'in Fig. 8

is particularly adapted tor the differential f shafts cfa motor vehicle and this form of device is'very similar to the form illustrated in Fig. 7, but with the exception that`the shaft 77 is'extended through an opening in a cap 78 which normally closes the outer end of hub or outer sleeve 7 9.

In this construction solid cylindrical rollers '8O are interposed between shaft 77 and sleeve 79. and truncated conical, rollers 81 are arranged between hardened metal bearing plates 82 at the ends of said rollers 80.

A roller' bearing of my improved construction is comparatively simple, can be i assembled or taken apart,c'an be readily adjusted to` take up wear and lost motion which may `develop after continued use, reduces frictionv between a shaft or axle and its bearing to a minimum, and can be effectively used in,various machines and structures and particularly lwhere it is desired to eliminate friction resulting from endthrusts between the shaft or spindle and its coperatingsleeve or bearing.

It will be readily understood that minor changes in the'size, form and construction of the various parts of my improved roller bearing can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims..

1. The combination with a shaft and sleeve, of a series of longitudinally extending rollers interposed between said shaft and sleeve, a. pair of bearing rings arranged adjacent to an end of the series of rollers, one

' yol saidl rings being held to rotate With Athe sleeve forms a trac'k for the longitudinally vextending rollers,

means for the other of said rings, and

and serves as Va .sec

12o l interposed between said shaft and` for adjusting one of said bearing rings toward the other.

' 3. The combination With a shaft and sleeve, of a series of longitudinally disposed rollers interposed between said shaft and sleeve, a pair of bearing rings arranged adjacent to an end of the series of rollers, one of said rings being held to rotate with the sleeve, a series of radially arranged rollers positioned between said bearing rings, a sie-eve removably secured in the shaft, which sleeve forms a track for the longitudinally extending rollers and serves as a securing means for the other of said rings, means for adjusting one of said bearing rings toward the other, and means for looking the adjusted ring after movement.

In testimony whereof I hereunto affix my signature in the presence of two witnesses,

-this 6th day of April, 1916.
